Not sure that I can offer advice. I'll tell you what I have done so far................I'll find out eventually if it was the right choice.

Not knowing any better, I went with most of the suggested suppliers from the Google doc BOM

Bought fasteners locally

The Misumi 20x20 frame, I took the easy option and bought it from Fermio Labs all cut, drilled and tapped. I believe that for me it was the best option. The ends are remarkably square (it does not take much of a squareness error on the end of a 20x20 to make a large squareness error at the end of a 500mm long beam), I only had to use kitchen foil shim a couple of times to get perfection.

I went with SKR 1.4's and TMC2209's from BigTreeTech as they are reccommended. Also a Pi4. If you do a search on the Discord channel, you will find much discussion especially in favour of SKR and why.

I'll find out if the Dragon hot end from Triangle Labs https://www.aliexpress.com/item/4000404170721.html?mp=1 was the best choice but again good things said about it.

That's it really, by the sound of it I'm newer to 3d printing than you.

I'm hoping that the last couple of things arrive from China soon......then I can get it finished.

The last unknown for me is "a reliable, cost effective source for good quality fillament"

Any pointers?
